3 Claims; (Cl.''198 -220 I This invention relates to a conveyer sectionfor reciprocating conveyors for conveying coal and other material-fromone point toanother, the general object of the inventionbeing to pro-Vide pan sections attached to carriages, the wheels of which engageadjustable track sections which cause the pan sections to assume anangle or curve according to the adjustment of the track sections.

Another object of the invention is to arrange the device on posts withmeans for adjusting the elevation of the device from the surface.

This invention also consists in certain other features of constructionand in the combina- 15 tion and arrangement of the several parts to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference 20 will be had to theaccompanying drawings wherein like characters denote like orcorresponding Figure 5 is a section on the line 5-5 of Figure In thesedrawings the numeral l indicates the main frame or base which issupported on the uprights 2 in an adjustable manner by means of thecup-shaped members 3, one of which is slidably arranged on each post andreceives the wedges i which are pressed into the member 3 40 by theflanged collar 5 surrounding the post and fastened to a flange of member3 by the bolts 6. Thus by tightening the bolts 6 the wedges are forcedinto the member 3 to adjustably hold the members 3 and the partsassociated therewith on the post. It will be understood that byloosening the bolts 6 the wedges will be released so that the member 3can be adjusted vertically on each post. A bolt 1 extends from eachmember and passes through a hole in 2. depending 50 flange I of themember I, this connection enabling the member 3 to be placed at an angleor inclination with respect to the posts. Adjustable brace bars 8connect lower portions of the posts with underparts of the member I .asshown more particularly in Figure 2.

A pair of track carrying members or sub-bases 9 are adjustably arrangedon the base I by beingrpivotedthereto as, at It at one corner of eachsub-base with, bolts ll passing through arcuate, slots 12.111 the basei. Thus. by loos ening' thebolts I I each sub-base or track carryingsection 9 can be adjusted vaboutthe pivot It and'then-bytightening thebolts the sub-base will be held inv adjusted position, a

Eachsubbase .or track.ca'rryingjsection has flanged outer 'rail"l3 and apair of flanged rails 14 which are placed relatively close togetherwiththe flanges extending toward each other.

A middle carriage section is shown at I an has the rollers It at itsends for engaging inter- 15 mediate parts of the main frame I and thiscarriage section is formed with a bar I! to which the forkedpart H? of abar I9 of a carriage section is pivoted as at 2!. A horizontallyarranged roller 22 is carried by the pivot 2|. 20 This section 20 is ofsubstantially triangular shape and carries a vertical roller 23 at itssmall end. A carriage section 24 formed on a bar with its ends turneddownwardly to carry the vertical rollers 25 is pivoted adjacent one endto the 25 outer end of the bar l9 as shown at 26, and a horizontalroller 22 is carried by the pivot 26. As will be seen from Figure 1 acarriage section similar to that shown at 20 is connected to the lefthand end of the section l5 and a carriage section similar to that shownat 24 is connected to the left hand end of this second carriage section2i]. A long centrally arranged pan section 2'! is fastened to thecarriage section l5 by bolts 28 and a shorter pan section 29 isconnected 3.; to each of the carriage sections 21! while shorter end pansections 39 are fastened to the two carriage sections 24 by ahorizontally arranged pin 3i passing through ears 32 projecting from thesection 2 this arrangement permitting the 4 outer pan section to swingup and down. As shown in Figure 1 the pan sections are providedwith wideends 33 for receiving the ends of the adjacent sections so as to permitfree movement of the inner pans. "15

The posts 2 are preferably in the form of screw jacks so that they canbe shortened and lengthened to properly engage the floor and ceiling ofa mine and it will be seen that the track sections or short bases can beadjusted to have the pan sections form different arcs or anglesaccording to the turn the conveyer is to make.

The wheel 23 of each carriage 20 engages under the flange of the rail 53while the outer wheel 25 of each carriage section 24 engages the flat 5part of each member 9 inwardly of the rail I3 and hers pivoted to theframe for adjustment to difthe horizontal wheels or rollers 22 of eachcarferent angles, means for holding said members riage 20 engage therails l4 under the flange in adjusted position, track forming railscarried thereof with the other wheel 25 of the carriage by said members,carriage sections pivotally 5 section 24 engaging the member 9 outwardlyof connected together and having wheels engaging the outer rail I4 asshown in Figure 1.
